Abstract: A soundproofing woody flooring comprises a top woody board, a sheet of sound insulating, vibration damping or buffering material glued to the top board, a perforated woody board glued to the sheet on the opposite side thereof from the top board, and a bottom buffering material glued to the perforated woody board on the opposite side thereof from the sheet. The buffering sheet preferably has one surface to which a fabric is bonded. More preferably, it has one surface to which a fabric is bonded, while the opposite surface of the sheet from the fabric is provided with small holes having a depth which is smaller than the thickness of the sheet.

Abstract: A flooring board assembly comprising a plurality of board parts, each board part having generally opposed tongue and groove formations thereon engageable with the groove and tongue formations, respectively, on an adjacent board part of the assembly. Each board part is further formed with a first notched surface below the tongue formation thereon and a second notched surface below the groove formation thereon. The corresponding first and second notched surfaces of any pair of adjacent board parts form a groove-like cavity upon engagement of the corresponding tongue and groove formations thereof. Each groove-like cavity is filled with a hot-melt resin which adheres to the corresponding first and second notched surfaces thereof.
